Document Type and Number:
WIPO Patent Application WO/2018/180837
Kind Code:
A1
Abstract:
Provided are: a method for manufacturing a water supply device, wherein nickel plating that is not covered with chrome plating can be easily removed; and a water supply device. According to the present invention, a predetermined potential is applied to a substrate made of a copper alloy while the substrate is immersed in an electrolytic solution, the surface of the substrate being nickel-plated or nickel alloy-plated and then further plated with chrome, and nickel plating or nickel alloy plating that is not covered with chrome plating is removed from a waterway inside a water supply device.
